Problems solved by technology

At present, in order to prevent the above symptoms, viscous polymer solutions such as hypromellose, chondroitin sulfate, and hyaluronic acid are often used as artificial tears to improve the state of the tear layer, but the therapeutic effect has certain limitations and cannot satisfactory
In recent years, the market has gradually introduced ophthalmic preparations that add traditional Chinese medicines, such as: borneol, flavescens, frankincense, Bupleurum, Codonopsis, chrysanthemum, Lingxiaohua, and white peony to relieve eye dryness. The mechanism is not yet clear, and the content of heavy metals cannot be effectively controlled, so it is still necessary to study a safer and more effective composition to protect the tear layer of the eye from damage

Embodiment 1

[0040] Preparation of eye drops containing polyvinyl alcohol with a mass concentration of 0.15%, a pH value of 6.5 to 7.0, and an osmolarity ratio of 1.0, the steps are as follows:

[0041] (1) Accurately weigh 1.2 g of polyvinyl alcohol as described in Table 1, add it to a 100L batching tank, raise the temperature to 130°C, and dissolve it in water for injection at a stirring rate of 90r / min to obtain solution A;

[0042] (2) Accurately weigh 0.25g D-glucosamine, 10.21g glycerin, 0.48g sodium chloride, 0.90g disodium hydrogen phosphate and 0.79g sodium dihydrogen phosphate in sequence, and add them to a 50L batching tank with a stirring rate of 90r / min , after being dissolved in water for injection, solution B was obtained, which was transferred to a 100L batching tank;

[0043] (3) Add water for injection to 800mL of the combined solution C, stir evenly, pass through a 5μm titanium rod filter, 0.45μm microporous membrane, 0.22μm microporous membrane, and aseptically fill to ...

Abstract

The invention relates to a medicinal composition for eyes. The medicinal composition comprises polyvinyl alcohol and D-glucosamine, wherein in percentage by mass, the content of the D-glucosamine in the composition is 0.015-0.04 wt%, preferably 0.02-0.035 wt%.

Description

technical field [0001] The present invention relates to an ophthalmic pharmaceutical composition. Background technique [0002] With the rapid development of economy and society, the air environment is getting worse and worse, which has contributed to the increasing number of ophthalmic diseases, especially for people who have been exposed to smog for a long time. The tear layer of the eyes is easily damaged, causing dry eyes, swelling and pain and other symptoms. At present, in order to prevent the above symptoms, viscous polymer solutions such as hypromellose, chondroitin sulfate, and hyaluronic acid are often used as artificial tears to improve the state of the tear layer, but the therapeutic effect has certain limitations and cannot satisfactory. In recent years, the market has gradually introduced ophthalmic preparations that add traditional Chinese medicines, such as: borneol, flavescens, frankincense, Bupleurum, Codonopsis, chrysanthemum, Lingxiaohua, and white peony...
